Currently, there is a very basic implementation of dying logic. To improve upon the current implementation, the first step is to add the logic to delete the marine entity once it dies and falls out of the screen.

It feels like there is between 200ms-500ms delay between pressing a key and seeing a response. Do others see the same thing?

You can see some visual artifacts in the background. I'm not sure what the cause is, but I suspect it may be lower down the stack.

The problem

Level map is incomplete. The complete map needs to be designed.

Expectations

• Level needs to be designed using Tiled map editor keeping the plot in mind. The level is for the space marine story line.
• The level should have increasing difficulty as the player progresses towards the end of the level.

The assets are available here. Feel free to add / modify assets if required.
For those who are new to Tiled, here is an excellent tutorial.

I have managed to compile on NixOS, but the resulting executable can't find its runtime dependencies (specifically libXrandr.so.2 but I suspect the issue will happen again with other dependencies).

Command:

nix-shell -p rustup pkg-config openssl alsaLib xorg.libX11 xorg.libXrandr cmake python3 freetype expat --run 'cargo run'

Hey team! I am super interested in trying space-menace but I can't get the dang thing to run! It compiles just fine for me, but won't run. 😞 Let me know if I'm doing something wrong or if I found a real bug we can fix.

The problem

Pincer but a little smarter, i.e. when hit by a bullet it should start moving in the direction of the player. It should be of different color than its basic version (Reddish may be).

Expectation

The implementation should be almost identical to that of basic Pincer. Some of the files related to basic Pincer to get started:

https://github.com/amethyst/space-menace/blob/master/src/components/pincer.rs
https://github.com/amethyst/space-menace/blob/master/src/entities/pincer.rs

Feel free to ask questions here or on the forum if you're interested in moving this along.

$SUBJ

Hello,

As a side project I'd like to learn Rust and thought a 2D game would be a fun first project.

When running Space Menace on Manjaro 20.0.1 I'm having issues with the size of the window (resizing doesn't help).

I updated Cargo.toml features default value to vulkan as described in the README

[features]
default = ["vulkan"]
metal = ["amethyst/metal"]
vulkan = ["amethyst/vulkan"]

It seems that somehow everything is scaled up, I noticed load_flier: scale = 2 in the terminal output though that seems unrelated (I set it to 1.0 with no change in the output).

I also noticed Guessed window DPI factor: 1 in the terminal output, though that seems to be standard from other issues I found on the Amethyst repo.

Any ideas of how I can get it to display correctly?

Terminal output below:

Just FYI, compiling on Windows 10 with Rust 1.36, target x86_64-pc-windows-msvc, both stable and nightly, gives the following error:

error: build failed

Hi,
I would like to report the same bug as for my previous issue #9, in spite of setting the features flag correctly in the Cargo.toml:

#...

[dependencies]
amethyst = { git = "https://github.com/amethyst/amethyst", features = ["nightly","vulkan", "json"] }
#...

Here's the backtrace - the only difference with that of #9 is that gfx-backend-metal is v0.2.3 instead of v0.2.1

error: failed to run custom build command for `gfx-backend-metal v0.2.3`

error: build failed

I also tried on stable and without release, but no cigar. This must be due to recent changes, because I managed to compile and run it when issue #9 was closed.

On my machine space marines uses about 50% of a processor. This seems high to me, although maybe it isn't an issue. Amethyst supports frame limiting as a way to reduce unnecessary cpu usage.

Just checked out this project, currently at 9c697897875545461749ca8a1080d419e1f4427e.

Straight cargo build did not work, had to run off nightly; then I hit:

It would be good to create a widget for viewing info about the scene (fps, number of sprites etc.) in debug mode. A translucent background and a text box should do the trick.

error: process didn't exit successfully: target\release\space-menace.exe (exit code: 101)

Note:

It opens the game window, but then it closes, and I tested it without the flag --release the error persisted

Version OS: Windows 10 20H2 19042.804

On running the game, player should land on the home screen which should have the following information:

• Name of the game
• Rules and instructions (just the key bindings for now)
• Instruction on how to start the game (something like, "Press 'Enter' to begin.")

The problem

Just like Pincer, add a new enemy, Stinger (alien flying enemy).

Expectation

• The Stinger should be able fly horizontally, both in right as well as left directions.
• It should move within fixed boundaries. The boundary limits can be hard-coded for now just like it is done for Pincer. Make sure that the Stinger's and the Pincer's boundaries don't overlap. The Stinger should appear preferably after the Pincer.
• On being hit 6 times by the bullet, it should die. Same explosion animation can be used as for Pincer.

The implementation should be almost identical to that of Pincer. The assets are available here.

Some of the files related to Pincer to get started:
https://github.com/amethyst/space-menace/blob/master/src/components/pincer.rs
https://github.com/amethyst/space-menace/blob/master/src/entities/pincer.rs

At the moment, whenever there is a drop in frames the characters noticeably slow down. When running in debug mode, it is common (at least on my laptop) for framerates to occasionally drop down to 30-40 fps. This causes a very noticeable and irritating jank in the characters' movements.

It would be desirable if the movements and animations advanced as a function of time passed, rather than number of frames passed.

• Entity velocities should be expressed in m/s, rather than m/frame
• Translation should be updated by adding velocity times delta seconds

I'd like to give this a go, if nobody is working on this yet. Any input is welcome. :)
